Let's do the first scan.

2

So now let's write our first in map command with this command.

3

We will scan the IP of the county the next computer for this.

4

Just open Kelly Linux user name root password tour and click terminal learn IP with if config and map

5

and your target IP.

6

Press the anarchy out so here we've entered our own IP information as the target IP.

7

So how can we find other threads and other targets.

8

So this is where we should probably talk a little bit about IP and network content we briefly mentioned

9

the concept of a rope before but let's go into a little more detail

10

these concepts are the basic concepts that you can probably encounter in just about all of your penetration

11

testing might sound a little boring at first but I really do want to help you master this subject right.

12

So we got to talk about what is a network Yeah I don't we've already defined network in that network

13

but let's dive a little deeper showing

14

so it's a communications system that device is established with each other in a certain area information

15

and system resources are shared among different users and data can also be transferred from one location

16

to another

17

and a network is formed just by connecting at least two devices now on the OS I reference model it's

18

located on Layer 3.

19

So what is the OS I reference model so if you haven't ever encountered it before the os i or Open Systems

20

Interconnection is a model that was developed in 1984 by ISO which is the international organization

21

where standardization

22

before you purchased a computer system prior to an OS a standard everything from cable to a network

23

hard drives to network operating systems were custom made for that company therefore different devices

24

could not communicate effectively with each other so that's why this model quickly became widely accepted

25

and also became a guide for network standards

26

so that way devices manufactured by different companies with the OS high standard

27

basically be able to communicate using the same protocols.

28

Now the ISI model consists of seven different layers and here they are Layer 7 application layer 6 presentation

29

where your 5 session layer for Transport Layer 3 network layer 2 data link layer 1 physical server now

30

will leave these layers here though throughout the course we will discuss os i additions when we get

31

to them in related topics now getting back to the end map scan that we perform it will occur on the

32

network layer which is OS I layer 3 now so with the scan and map we'll try out the first 1000 TTP ports

33

that are most commonly used which ports are available and what their status is whether it's on or off

34

and then the service names that we'll be using those ports the 1000 DCP ports used by N map will come

35

by to default and if we want to change the list of ports used we just need to modify the file user share

36

and map and map services I don't recommend that though.
